Wärtsilä Corporation Trade &Technical Press 25 July, 2002
To increase the reliability of power supply to its customers in Raton, New Mexico, USA, Arkansas River Power Authority (ARPA) has contracted with Wärtsilä for the purchase of a 7 MWe gas-fired peaking power plant. The plant will be used for intermediate peaking and back-up for a 7.5 MWe coal-fired power plant.
The pre-engineered and pre-packaged power plant will feature the Wärtsilä 20V34SG gas engine. This engine is similar to Wärtsilä’s successful 18V34SG with the addition of two cylinders. The plant will operate for, up to, 5000 hours per year, the installation will be completed during the first quarter of 2003.
“This contract solidifies the continued growth of our power plants for peaking power use. The Raton plant will enable ARPA to overcome critical issues such as; output, emissions, and continued peak performance,” said Frank Donnelly, Vice President of power plants for Wärtsilä in North America. “We were awarded the contract due to our faster implementation time, the plant’s lower operating costs and increased control, especially when demand for electricity is at its highest.”
The contract was won in the face of tough domestic and international competition. Both gas turbine and gas engine power plants were considered. In the end the Wärtsilä gas engine solution won due to Wärtsilä’s expertise and experience of supplying reliable power at high altitudes.
The Raton plant will be operating at 6,700 FASL (feet above sea level). ARPA considered that the Wärtsilä technology’s ability to maintain ISO heat rate and output at this elevation as extremely significant.
Wärtsilä has won orders, from across the United States, for more than 250 MWe for peak shaving plants to be used for power supply when demand is at its highest.
These innovative power plants are the first reciprocating engine plants to be tailored to the needs of the larger gas-fired peaking market. These pre-packaged power plants were developed to address the unique peak and intermediate energy requirements of North America.
When compared to the traditional technology used in similar U.S. power plants, Wärtsilä’s plants offer faster delivery times, lower emissions, lower operating costs, no continuous water requirements, an approximate 23 percent increase in efficiency and a scalable design that more closely matches customer’s needs.
